Spacing convention between element name and equal sign (div= versus div =)

[mmzoo]

I noticed inconsistency when my colleagues, who are used to Haml, transision to Slim:

Notice the space before the = sign:

/ Good
div = 'This is what the official slim documentation uses consistently'

/ Bad
div= 'This works, but it should probably not be encouraged.'

/ Not affected
a href="This is still fine though, because it is an attribute"

I also noticed that my syntax highlighter (TextMate) doesn't properly recognize the non-spacing version:

Would this cop be something worth implementing?

(I tried twice to bugfix some rubocop internals and failed miserably somewhere in the AST 😂, so I cannot promise a PR, but I will try if you think this cop makes sense :)
